NTK uses ceramic engineering and manufacturing controls from raw material through finished sensor production, and each oxygen sensor is tested during manufacturing to meet or exceed OE specifications. This part cross-references Bosch 15711 and Delphi ES20036 for the same application.\u003c\/p\u003e\u003cp\u003eCompatible With select Toyota applications, this oxygen sensor fits 1989-1991 Toyota Pickup, downstream, and 1988-1989 Toyota MR2, upstream. Use it when replacing a heated oxygen sensor on a Toyota Pickup or Toyota MR2 with the listed configuration and emissions setup. The NTK 24539 is built for direct-fit service where the original sensor uses the same mounting style and wiring layout.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn or slow-responding oxygen sensor\u003c\/li\u003e\n\u003cli\u003eRestoring proper air-fuel ratio feedback to the engine control system\u003c\/li\u003e\n\u003cli\u003eAddressing sensor-related fault codes or emissions concerns\u003c\/li\u003e\n\u003cli\u003eCorrecting drivability issues tied to inaccurate exhaust oxygen readings\u003c\/li\u003e\n\u003cli\u003eServicing direct-fit Toyota oxygen sensor applications with the listed configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle year, model, position, and emissions notes before ordering.
